Graphing Utility Recommendation

Rebecca — Mon, 10 Feb 2014 13:00:09 +0000

Here at the start of another string of posts I wanted to recommend a graphing program I’ve used pretty intensively recently: Graphmatica. It’s shareware with a license fee of $25, and in particular if you want to graph complicated piecewise-defined functions it’s the best thing around. The graph below was entered as a single function.

The messy cropping job is all me. Graphmatica is lightweight and versatile, and if you have some experience with LaTeX you’ll be up and running in no time.

Mathlinks

I had a page on my Notre Dame website called mathlinks. This isn’t the same collection but it falls into the same category.

The math genealogy page is always interesting reading.
A translation of Euclid’s Elements by Richard Fitzpatrick.
The University of Michigan’s Historical Mathematics Collection.
A page of famous codes and ciphers.
Animated GIF that I like for no good reason
An excellent site to point students to is Understanding Mathematics by Peter Alfeld at the University of Utah.
For review of high school skills assumed by the text (such as polynomial long division), I have pointed my students to S.O.S. Math, which has an easy to navigate layout and explanations plus exercises with answers.
The Quine Page: self-reproducing code. Not updated in a long time but features a lot of examples
Fooplot online graphing calculator; allows export of graph as svg, eps, pdf, or png
Another online graphing calculator
Java Graphers, applet graphing calculators that include 3D capability

Calculus handouts

Here are a few handouts I’ve used in the past to teach parts of calculus.

Relating latitude and longitude to spherical coordinates. Bonus appendix about great circles.
Trigonometry review for calculus students.
A guide to curve sketching.
Painfully detailed examples of surface integration.
